What happened to this App? – Jigsaw Puzzles - Puzzle Games Review

This was my favorite puzzle app and then something went wrong. I start a puzzle and when I don’t finish it and come back to it it’s either gone or competed?? All my other puzzles that I have completed are not in my library or if they are it says they are not completed. I have tried restarting it and reinstalled it but nothing is working. Wondering if their have been others with this same problem?
